Comment 59 for bug 1728354

This file is "system compressed", so you need the systcomp plugin to read it. It is a system dll which has three symlinks and a short name, and it also has an integrity tag.

Most file-level backup programs will decompress the file, and lose its special attributes, so you will not be able to restore it.

Which error do you get when you copy this file by a regular cp command ?

I usually use ntfsclone to save an ntfs partition. For instance :
(the partition /dev/sdxx has to be unmounted beforehand)

sudo ntfsclone -s -O - /dev/sdxx | gzip > saved-image.gz

and you can restore it by (notice the isolated final "-") :

gzip -cd saved-image.gz | sudo ntfsclone -r -O /dev/sdxx -

In your case, most of the files are already compressed, so you will save time by not processing through gzip.
